Can you help me with my project?
You can book a discovery package where we can do a dedicated analysis and answer all of your questions. Stackup is not a professional services firm, but if you use our infrastructure we'll do our best to get you off the ground. Dedicated support options are also available as an add-on service.
Why do I need more than one app key?
Each API key corresponds to a single network. So if you have only one API key, you can only access one network with a single set of security rules in your dashboard. Sometimes, you will want multiple API keys to access the same network. For example, you may want to have a different API key for your backend services than your front end application.
What blockchains does Stackup support?
Stackup supports Ethereum, Polygon, Arbitrum, Optimism, Avalanche C Chain, and BnB Smart Chain (BSC).
Can I add a fee to my paymaster or do revenue share?
Yes, but right now this isn't self-serve. Please contact us at founders@stackup.sh.
